Unfortunately, DL ontologies are difficult to learn from data and time-consuming to encode manually. As a result, ontologies for broad domains are almost inevitably incomplete. In recent years, several data-driven approaches have been proposed for automatically extending such ontologies. One family of methods rely on characterizations of concepts that are derived from text descriptions. While such characterizations do not capture ontological knowledge directly, they encode information about the similarity between different concepts that can be exploited for filling in the gaps in existing ontologies. To this end, several inductive inference mechanisms have already been proposed, but these have been defined and used in a heuristic fashion. In this paper, we instead propose an inductive inference mechanism which is based on a clear model-theoretic semantics, and can thus be tightly integrated with standard deductive reasoning. We particularly focus on interpolation, a powerful commonsense reasoning mechanism which is closely related to cognitive models of category-based induction. Apart from the formalization of the underlying semantics, as our main technical contribution we provide computational complexity bounds for reasoning in EL with this interpolation mechanism.<\/jats:p>","DOI":"10.24963\/kr.2020\/51","type":"proceedings-article","created":{"date-parts":[[2020,8,20]],"date-time":"2020-08-20T00:39:16Z","timestamp":1597883956000},"page":"506-516","source":"Crossref","is-referenced-by-count":1,"title":["Plausible Reasoning about EL-Ontologies using Concept Interpolation"],"prefix":"10.24963","author":[{"given":"Yazm\u00edn","family":"Ib\u00e1\u00f1ez-Garc\u00eda","sequence":"first","affiliation":[{"name":"Cardiff University"}]},{"given":"V\u00edctor","family":"Guti\u00e9rrez-Basulto","sequence":"additional","affiliation":[{"name":"Cardiff University"}]},{"given":"Steven","family":"Schockaert","sequence":"additional","affiliation":[{"name":"Cardiff University"}]}],"member":"10584","event":{"number":"17","sponsor":["Artificial Intelligence Journal","Principles of Knowledge Representation and Reasoning Inc.","Association for Logic Programming","Center for Perspicuous Computing","European Association for Artificial Intelligence","Ontopic - The Virtual Knowledge Graph Company"],"acronym":"KR-2020","name":"17th International Conference on Principles of Knowledge Representation and Reasoning {KR-2020}","start":{"date-parts":[[2020,9,12]]},"theme":"Artificial Intelligence","location":"Rhodes, Greece","end":{"date-parts":[[2020,9,18]]}},"container-title":["Proceedings of the Seventeenth International Conference on Principles of Knowledge Representation and Reasoning"],"original-title":[],"deposited":{"date-parts":[[2020,11,5]],"date-time":"2020-11-05T16:18:41Z","timestamp":1604593121000},"score":1,"resource":{"primary":{"URL":"https:\/\/proceedings.kr.org\/2020\/51"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2020,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/kr.2020\/51","relation":{},"subject":[],"published":{"date-parts":[[2020,7]]}}}
